/* ANSI X12 is similar to EDIFACT, except that:
 * - The header, ISA (analogous to a combination of UNA and UNB) is always present
 * - Because ISA is always present, the encoding rules are always present
 * - Where EDIFACT uses UNZ, X12 uses IEA
 * - Where EDIFACT uses UNG/UNE, X12 uses GS/GE
 * - An additional group, ST/SE, is used to mark a "transactional set"
